OEX Starter Motor 24V 11 Tooth CW Delco 50MT Style Pre Lube DXS9156

The OEX starter motor DXS9156 is a 24V unit in 50MT style, set up with 11 teeth and clockwise rotation. It is listed as a new starter motor with a 3 hole starter mount type, 126mm mount centres A, B and C, and a 92mm flange diameter, so it suits applications where those dimensions match the existing unit.

This starter motor is specified for Delco applications and includes a pre lube pump note, with the product described as 50MT fitted with Pre Lube Pump. The key size and setup details are important here: overall length is 515mm, pinion diameter is 56mm, and pinion at rest is 46mm, all of which should be checked against the removed starter before purchase.

OEX lists this part as 8.5kW and 34.4kg, which places it in a heavy-duty rotating electrical category rather than a light passenger vehicle starter. It is supplied under part number DXS9156 and is backed by a 3 year passenger / 1 year commercial warranty, so confirming the voltage, mounting pattern, and Delco application remains the safest way to order correctly.

Application and Buying Notes

Before ordering, compare the part number DXS9156 with the starter you are replacing, then check the 24V electrical system, 11 tooth pinion, and clockwise rotation. Those three points, together with the 50MT series and Delco suitability, are the most useful identifiers for avoiding a mismatch.

Physical dimensions matter with heavy-duty starters like this one. The 3 hole mount, 126mm mount centres across A, B and C, 92mm flange diameter, 16mm mount hole diameter, and 515mm overall length all need to line up with the original starter and the engine bellhousing arrangement.

Because the listed fitment covers large equipment and industrial engine applications, a visual comparison is sensible even when the model name appears in the application list. Match the pinion diameter of 56mm, pinion at rest of 46mm, and the overall 34.4kg weight where possible, as these details help confirm you are looking at the correct style of starter.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number DXS9156 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

For part number DXS9156, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment with part number DXS9156, the 24V electrical rating, 11 tooth clockwise configuration, 3 hole mount, and the specific Delco 50MT style application before purchase.
